At the first floor, I motioned for Jack to continue heading down, then turned toward the door. He caught my arm, but I motioned that I’d follow in a moment. I jogged to the first floor door, opened it as far as it would go, released it and turned to race after Jack. As we rounded the midflight turn, Jack glanced up. The door I’d opened was slowly swinging shut, where the agents would see it and assume we’d gone that way. Jack nodded his approval.

Above us, several sets of shoes clomped down the steps at double-time. When we reached the basement door, Jack waved me against the wall. He opened the door slowly and silently. We slipped through and he eased it shut behind us.

We turned to survey our surroundings. A typical industrial basement: big, semidark, full of wheezing, clanking machinery. Helpful signs on the wall indicated points of interest: furnace, laundry, storage, deliveries. Jack jabbed a finger at the last.

As we turned the first corner, a grating squeal cut through the mechanical roar, growing louder by the second. We looked around. To our left was a hall lined with old office equipment. We took refuge beside a filing cabinet.

The squeal turned to a steady squeaking. Wheels in need of oiling. Seconds later, the sound began to recede. I leaned out to see an employee wheel a metal cart of laundry onto an elevator. We waited until the doors clanked shut before we took off.

After years of being the hunter, it was strange being pursued—and by cops, no less. I felt an uncomfortable inkling of shame, not unlike when I was nine and Amy talked me into swiping a candy bar from the store. I hadn’t been caught. I’d even snuck back later and returned it, without her knowing. Running from these agents, I felt the same twinge, mitigated only by the reminder that I wasn’t committing a crime, but trying to solve one.

My ruse with the first-floor door wouldn’t stymie the FBI for long, but it had bought us a few critical minutes. We made it to the delivery loading dock without incident. From there, escape was a simple matter of unlocking the exit door and walking out.

We stepped into the fading light and found ourselves at the foot of a small flight of stairs.

“I’ll look. Wait here.”

I nodded. Though I was quite capable of scouting, I was the lawyer who’d snuck out. No one was looking for a janitor.

Jack climbed the steps and disappeared. By the time I’d slipped my shoes back on, he’d reappeared at the top. He waved me up. I was just high enough to peek over ground level when two men in maintenance jumpsuits walked around the corner. I ducked so fast I nearly fell backward down the steps. Jack started to follow, then let out an obscenity.
